- To all whomi'it may concern:4 i

.Be it known that I, OSCAR H'. KARCHER, a citlzen of the United States, residi'n at Lansing, 1n the county of Ingham and tate of Michigan, have invented a new and useful Ball-Bearing, of which the following is a l specification.

tion devices, and 'the primary object of the invention and the prime feature thereof resides in so arrangingand constructing theA parts of the bearing that the shaft supported thereby may rotate freelyandwithout binding even though it be slightly out of alinement With the axisof the bearing,

The bearing embodying the invention is universal in its applicationinasmuch as it may be used'n a number of different Ways such for example, a bearing for a machine shaft, for a Wheel, or for other similar purposes, and in other similar relations.

Broadly speaking, the invention resides in the provision of a bearing comprlsing an outer, bearing member and an lnner bearlng member, said inner bearing member being free to rotate and to oscillate laterally Within the said outer bearing, the shaft Eof course being' passed through the inner bearing 4member and the said memberbeing designed to rotate with the shaft.

In the accompanying drawings, Figure l is a view in side elevation and partly 11i section of the bearing embodying the invention. Fig. 2 is a vertical sectional vieW` taken axially therethrough, and Fig. 3i is a detail edge view of one ot' the annular ball bearing receiving. frames.

As shown in the drawings, the bearing embodying the invention is .comprised in part ot' an' outer annular bearing member which is indicated by the numeral 5, and which is formed `with substantially `V-shaped ball races 6, these racesibeing formed in" its inner peripheral surface and being located in parallel planes- The vbearing further embodies an inner *bearing member which is indicated by :the mnneral 7 and is also in the form oi an annulus, it having a bearing surface S which is convex from sideA to side and at all point-mis delined by the arc cfa circl" having its center. coincident with the axis'oi' the inner bearing member 7. Ball bearings 9 are arranged one Within each o f the, ball races 6 and extend i n a continuous series' in the* respective ball races and bear also againstthe transversely convex bearing-.surface ot the inner 'bearing member 7, it being understood from the fore .gging description and also from the drawmgs, and particularly Fig. 2 thereof, that 'the said inner member 7 is not only free to It is the object of the present invention to c improve generally theconstruction of shaft'l bearings of that class embodying antifric rotate within the said bearing member but is also free to oscillate laterally therein or spreed and which form, between the said side portions 10. an annular series of, ball benl-imgreceiving compartments. it being understood that one ot the balls 9 is dispos al `within each compartment ot' each ball receiving frame. and that the avebs ll serve to separate the balls -from contact one with another. As' heretofore explained. the inner bearing member 7 is adapted'sto oscillate laterally with respect tothe outer memberwi whereby to compensate 't'or the non-alinement ot' the shaft. supported b vthe bearing. with the axis oi' the bearing'as an entirety. and in order to limit this oscillatory movement or plaiv otV theinnerf bearing meniber 7 with respect t) the meniber 5, thesaid member `7 is formcdin its bearing surface and at one side With an annular seat Yor groove'lQ in which is removably seated or ,fitted a ring 13, i't being understood that this ring. should the inner member T'be os# cillated to a considerable degree, contacts wit l1 the balls ot' the adjacent set and will prevent further oscillation of the set in the bearing member.

lt Will be understoml'that the V-shaped bearing and 'the bearing surfaces ot' `the racesf A lVhat is claimedlisy- 1. In a. bearing of the class described, an annular bearing memberI formed with ball races and an annular rib separating the races, an inner, bearing membelwhaving a bearing surface which at all points is d e-l coincident with the axis of the said inner 4said outer mel-uber. ,the inner member being 'free to oscillate and rotate. within the outer ball races lessen the friction lbetween the.

member. balls within thc'ball races ot' the connecting webs 1l Which arequi-distantly fined by the arc of a circle having its center member, and anelement carried removably upon the bearing surface of the inner mem-A ber engageable. with the balls in one race whereby to limit the oscillatory movement of the saidinner member.

2. In a bearing of the class described, an annular bearing member formed of ball races and with a rib separating thel races, an inner bearing member having a bearing surface which at all points is defined by the arc of a. circle having its center coincident` with the axis of the said inner member, annular frames arranged between the two members y and havingeach a plurality of ball receiving compartments, balls within the said compartments, and seating in the races, the inner member being free to oscillate and to rotate within the outer member, and an element carried removably upon the bearing surface of the inner member and engageable -with the balls in one race whereby to limit the oscillatory movement of the said inner i member.

3. In a bearing of the class described, an

annular bearing member formed with ball races and with an annularl rib separating theraces, an inner bearlng member havlng a bearing surface which at all points is delined by the arc of a circle having .its center coin- `aident with the axis of the said inner member, integral annular frames arranged between the two members and having each a plurality of ball receiving compartments,

balls-confined one within each of said compartments and seating the races, the inner member being freeto oscillate ,and to rotate within the said outer member, and an element carriedy removably upon the bearing surface of the inner member and engageable withI the balls in one race whereby to limit the oscillatory movement of the said inner member.

4. In afbe'aring of the class described, an outer annular bearing member formed with ball-races, an inner bearing member having a bearing surface which at all points is delined by the are of a circle having its center coincident with the axis ofthe said inner member, the said outer annular bearing member being formed also with an integral annular rib separating the ball races, annuinner member. l

6. In a bearing of the class described, an

.outer member whereby to limit the oscillatory movement of the inner member.

5. In a bearing ofthe class described, an outer annular bearing member formed with ball races and with an annular rib separating the races, an inner bearing member having a bearing surface whieh at all points is defined by the are of a circle having its center coincident with the axis of the said inner member, annular frames .arranged between the two members and having each a plurality of ball. receiving compartments, balls within the said compartments and 'seating in the races, the inner member being free to oseillate and to rotate within the outer me1- ber, and a ring removably carried ponthe bearing surface of the inneranember and engageable with the balls in one race whereby to limit the oscillatory movement ofthe said annular bearing member formed with 'a ball race, an inner bearing member having a bearing surface which at all points is defined by the are of a circle-having its center coincident 'with the axis of the said inner member, balls within the ball race of the outer member, the inner member being free to rotate'and oscillate within the outer member, and an annulus carried removably upon the bearing surface of the inner member and engageable with the balls whereby to limit the oscillatory movement of the said inner member.`

In testimony that I claim the foregoing l as my own, I .have hereto aflixed my signature 1n the presence oftwo Witnesses.
